Abstract

Cette buse comporte un élément chauffant électrique avec un canal interne 24 à travers lequel s'écoule la matiere plastique fondue, une enveloppe 10, 11 et des orifices de sortie 5 dans la région de son extrémité avant, la section de cet élément chauffant diminuant en direction de la pointe de la buse. Selon l'invention, une résistance chauffante 9, liée à l'enveloppe, est montée avec une disposition centrale, la section de cette résistance diminuant vers son extrémité avant, et il est prévu, entre la partie de section décroissante et la partie de section courante de ladite résistance, une autre partie 16 présentant une surface importante, et possédant une section égale ou supérieure à la section courante de la résistance. Cette partie 16 est située au voisinage des orifices de sortie 5, délimités par des languettes qui prolongent la partie avant 10 de l'enveloppe.This nozzle comprises an electric heating element with an internal channel 24 through which the molten plastic material flows, a casing 10, 11 and outlet orifices 5 in the region of its front end, the section of this heating element decreasing by direction of the tip of the nozzle. According to the invention, a heating resistor 9, linked to the casing, is mounted with a central arrangement, the cross-section of this resistor decreasing towards its front end, and provision is made, between the part of decreasing section and the part of section current of said resistor, another part 16 having a large area, and having a section equal to or greater than the current section of the resistance. This part 16 is located in the vicinity of the outlet orifices 5, delimited by tabs which extend the front part 10 of the envelope.
